After 35 Years of Experimentation, This Kerala Priest’s New Rubber Variety Offers a Double Yield!

Home to the highest number of rubber plantations in the country, Kerala accounts for almost 90 per cent of India’s total natural rubber production.

Brought to India during the British era, the crop continues to remain a great favourite amongst the farmers in the state, with generation after generation taking the reins of its cultivation and production forward.

Named ‘Thadathil’, Father Thomas, who hails from Cheenikkuzhi, spent three-and-half decades researching and conducting experiments before finally developing the new variety.

According to local daily Mathrubhumi, the new rubber variety offers double the profit, in terms of not just the yield but growth of the plants as well, in comparison to the commonly cultivated variety RRII-105.

It all started in 1983 when Father Thomas purchased 350 saplings of RRII-105 variety from the Rubber Board in Kerala. While the plants were growing, he noticed that one particular sapling grew better than all the other ones and generated about 1.75-litre latex per day once the tapping began.

Intrigued, he cut the vertical part of the tree trunk and discontinued the rubber tapping. Meanwhile, new shoots had started growing nearby the tree, that was used by Father Thomas for budding in the rubber saplings planted across a patch of land.

Over a period of seven years, he observed that the trees shot up to 57cm with visibly thicker barks and generated close to 25 kg of dry rubber, once tapping begun. He also noted that all the 130 experimental trees not only produced an equal and consistent amount of latex but grew to a similar size as well.

The man has also opened a nursery with saplings grown using bud woods from the same tree. After hearing about the ‘Thadathil’, farmers have been frequenting his plantation to see the tree for themselves.

In fact, Father Thomas’s chance discovery and subsequent achievements have found its way to publications like ‘Rubber Asia’ and the ‘Rubber’ magazine of Rubber Board. Presently, he is trying to acquire the patent for a new variety.

According to Cissy P. Mathew, who is the Assistant Director of Agriculture in Elamdesam Block, an unusually high production rate was observed during their study in Father Thomas’ plantation.

She also added that a scientific study is required to decipher the actual reason behind the phenomenon, which could either be a genetic mutation or overuse of fertilisers.
